For computer users, a few mouse clicks could mean the difference between staying online and losing Internet connections this summer.

Unknown to most of them, their problem began when international hackers ran an online advertising scam to take control of infected computers around the world. In a highly unusual response, the FBI set up a safety net months ago using government computers to prevent Internet disruptions for those infected users. But that system is to be shut down.

The FBI is encouraging users to visit a website run by its security partner,http://www.dcwg.org , that will inform them whether they’re infected and explain how to fix the problem. After July 9, infected users won’t be able to connect to the Internet.

Pinterest, the newest social network to take the world by storm, is coming to Facebook in a unique iteration: an app that redesigns your News Feed, Timeline, friend list and multimedia pages to look like Pinterest’s home page.

Pinview’s app is one of Facebook’s newest apps for Timeline, and resides within the Facebook browser. This means that you can toggle between your normal views of Facebook and Pinview’s Pinterest-esque design without having to disable an app or remove an add-on like you might have had to do in the past.

Priced at just $99.99, the Mini Boombox is much cheaper than many comparable products. This makes it a great buy iconsidering its larger-than-life sound reproduction. I don’t plan to purchase a Mini Boombox for myself, as I already own a couple similar speakers, but it would be a reasonably-priced and solid optionfor business users looking for a quality wireless speaker that doesn’t cost an arm and a leg.

Radiation from a mobile phone call can make brain regions near the device burn more energy, according to a new study.

Cellphones emit ultra-high-frequency radio waves during calls and data transfers, and some researchers have suspected this radiation — albeit inconclusively — of being linked to long-term health risks like brain cancer. The new brain-scan-based work, to be published Feb. 23 in the Journal of the American Medical Association, shows radiation emitted from a cellphone’s antenna during a call makes nearby brain tissue use 7 percent more energy.

Physicists Andrew Cleland and John Martinis from the University of California at Santa Barbara and their colleagues designed the machine—a tiny metal paddle of semiconductor, visible to the naked eye—and coaxed it into dancing with a quantum groove. First, they cooled the paddle until it reached its “ground state,” or the lowest energy state permitted by the laws of quantum mechanics (a goal long-sought byphysicists). Then they raised the widget’s energy by a single quantum to produce a purely quantum-mechanical state of motion. They even managed to put the gadget in both states at once, so that it literally vibrated a little and a lot at the same time—a bizarre phenomenon allowed by the weird rules of quantum mechanics.

Science and its publisher, AAAS, the nonprofit science society, have recognized this first quantum machine as the 2010 Breakthrough of the Year. They have also compiled nine other important scientific accomplishments from this past year into a top ten list, appearing in a special news feature in the journal’s 17 December 2010 issue. Additionally, Science news writers and editors have chosen to spotlight 10 “Insights of the Decade” that have transformed the landscape of science in the 21st Century.

“This year’s Breakthrough of the Year represents the first time that scientists have demonstrated quantum effects in the motion of a human-made object,” said Adrian Cho, a news writer for Science. “On a conceptual level that’s cool because it extends quantum mechanics into a whole new realm. On a practical level, it opens up a variety of possibilities ranging from new experiments that meld quantum control over light, electrical currents and motion to, perhaps someday, tests of the bounds of quantum mechanics and our sense of reality.”

The Web surfing history saved in your Web browser can be accessed without your permission. JavaScript code deployed by real websites and online advertising providers use browser vulnerabilities to determine which sites you have and have not visited, according to new research from computer scientists at the University of California, San Diego.

The researchers documented JavaScript code secretly collecting browsing histories of Web users through “history sniffing” and sending that information across the network. While history sniffing and its potential implications for privacy violation have been discussed and demonstrated, the new work provides the first empirical analysis of history sniffing on the real Web.

“Nobody knew if anyone on the Internet was using history sniffing to get at users’ private browsing history. What we were able to show is that the answer is yes,” said UC San Diego computer science professor Hovav Shacham.
The computer scientists from the UC San Diego Jacobs School of Engineering presented this work in October at the 2010 ACM Conference on Computer and Communications Security (CCS 2010) in a paper entitled, “An Empirical Study of Privacy-Violating Information Flows in JavaScript Web Applications”.

History Sniffing

History sniffing takes place without your knowledge or permission and relies on the fact that browsers display links to sites you’ve visited differently than ones you haven’t: by default, visited links are purple, unvisited links blue. History sniffing JavaScript code running on a Web page checks to see if your browser displays links to specific URLs as blue or purple.

History sniffing can be used by website owners to learn which competitor sites visitors have or have not been to. History sniffing can also be deployed by advertising companies looking to build user profiles, or by online criminals collecting information for future phishing attacks. Learning what banking site you visit, for example, suggests which fake banking page to serve up during a phishing attack aimed at collecting your bank account login information.

Sounds pretty creepy, but it seems there’s some actual utility in the process to aid in vitro fertilization right now.

From the link:

Scientists from Spain’s Universitat Autònoma de Barcelona (UAB), along with colleagues from the Spanish National Research Council, have successfully developed an identification system in which mouse embryos and oocytes (egg cells) are physically tagged with microscopic silicon bar code labels. They expect to try it out on human embryos and oocytes soon.

The purpose of the system is to streamline in vitro fertilization and embryo transfer procedures. If egg cells and embryos can be quickly and easily identified, then things should run much smoother, and success rates should be higher.

The research, published online in Human Reproduction, represents a first step towards designing a direct labeling system of oocytes and embryos. The objective was to develop a system that minimizes risks when identifying female gametes and embryos during in vitro fertilization and embryo transfer procedures, to reduce the phases of the clinical process requiring control and supervision by two embryologists.

Not only is the TSA a ridiculous bureaucratic mess that isn’t making anyone any safer at airports or in the skies, plus it’s now turned into an organization demanding organized “legal” molestation. It’s also very possibly damaging your health if you want to avoid the unwanted groping.

From the link:

As millions of U.S. travelers get ready for the busiest flying day of the year, scientists still can’t agree over whether the dose of radiation delivered by so-called backscatter machines is significantly higher than the government says. This is despite months of public debate between the White House, the U.S. Food and Drug Administration, and independent scientists.

Full-body scanners have been installed at many U.S. airports. The machines use either low-energy, millimeter wavelength radiation, which is harmless, or X-rays, which can potentially be hazardous. X-rays can ionize atoms or molecules, which can lead to cancerous changes in cells. Even if the government has significantly underestimated the dose of radiation delivered by an X-ray scanner, it is likely to be relatively small.

And more:

In April, four scientists at the University of California, San Francisco, wrote a public letter to the White House warning that the government may have underestimated the dosage of ionizing radiation delivered to a person’s skin from a backscatter machine by one or two orders of magnitude. The scientists, who have expertise in biochemistry, biophysics, oncology, and X-ray crystallography, pointed out that the government’s estimate was based on radiation exposure for the entire body. During scanning, the majority of radiation will be focused on the surface of the body, meaning a more concentrated dose of radiation is delivered to the skin.

I’ve blogged about this morethanonce, but if you need the ultra-quick version — China supplies pretty much the entire world with rare earth minerals, elements that are used to manufacture vital electronics and computing parts, because it’s been doing so very, very cheaply for a long time. Recently the nation has used its rare earth monopoly as an economic bludgeon, most notably against Japan and the United States.

We know the U.S. and Australia, among other countries, have rare earth element resources. Now that we know just how rare earth rich the U.S. is, it’s time to seriously ramp up domestic production and get off the cheap Chinese teat.

From the fourth (and last) link:

Approximately 13 million metric tons of rare earth elements (REE) exist within known deposits in the United States, according to the first-ever nationwide estimate of these elements by the U.S. Geological Survey.

The report describes significant deposits of REE in 14 states, with the largest known REE deposits at Mountain Pass, Calif.; Bokan Mountain, Alaska; and the Bear Lodge Mountains, Wyo. The Mountain Pass mine produced REE until it closed in 2002. Additional states with known REE deposits include Colorado, Florida, Georgia, Idaho, Illinois, Missouri, Nebraska, New Mexico, New York, North Carolina, and South Carolina.

“This is the first detailed assessment of rare earth elements for the entire nation, describing deposits throughout the United States,” commented USGS Director Marcia McNutt, Ph.D. “It will be very important, both to policy-makers and industry, and it reinforces the value of our efforts to maintain accurate, independent information on our nation’s natural resources. Although many of these deposits have yet to be proven, at recent domestic consumption rates of about 10,000 metric tons annually, the US deposits have the potential to meet our needs for years to come.”

REE are a group of 16 metallic elements with similar properties and structures that are essential in the manufacture of a diverse and expanding array of high-technology applications. Despite their name, they are relatively common within the earth’s crust, but because of their geochemical properties, they are not often found in economically exploitable concentrations.

Can you name some brands whose mobile advertising has been very engaging and useful for the user?

One of my favorite campaigns recently was one that was run by Dunkin’ Donuts, where they were releasing a new iced latte product to the market. When the user went to the screen, the screen frosted over, very much like the frost on the side of a glass for your iced latte, and then with your finger you wiped the frost off the screen.

This was art that was reproducing the experience that people have in the real world, and it brings a real joy to people.

If you can combine the engaging nature of the medium together with that joy, together with the message that ties directly with this product you’re offering, that’s very powerful for the advertiser.

I have the feeling one person’s joy is another person’s total pain-in-the-ass with this campaign.

And a to a very large extent, the violated are willfully doing it to themselves. I really wonder, do most people have no idea what data mining is and what it can do given a substantial amount of personal information? Maybe the boy-wonder CEOs of Google and Facebook are right, and most people just don’t care.

From the link:

In this cell-phone-centric age, your friends might learn that you’ve gone to see a movie when you arrive at the theater and check in on Facebook or Foursquare. But that’s probably too late to function as anything more than a boast. An iPhone app called Blaze Mobile Wallet tells them the instant you book a ticket in advance, giving them time to respond and meet you there.

When users pay for a reservation using the app, which debits funds from a prepaid account, a Facebook post lets friends know all the details: film, theater, and show time. “It makes it more likely that friends will join them at the movie,” says Michelle Fisher, CEO of Blaze Mobile, one of a slew of companies exploring how cell phones that act as wallets can encourage new connections between friends—and between businesses and their customers.

A robot known as “Cody” successfully wiped away blue candy from a test user’s legs and arms without being too forceful, researchers from the Georgia Institute of Technology (led by assistant professor Charlie Kemp) reported at the 2010 IEEE International Conference on Intelligent Robots and Systems (IROS) conference last month.

UPTON, NY — Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and Los Alamos National Laboratory have fabricated transparent thin films capable of absorbing light and generating electric charge over a relatively large area. The material, described in the journal Chemistry of Materials, could be used to develop transparent solar panels or even windows that absorb solar energy to generate electricity.

The material consists of a semiconducting polymer doped with carbon-rich fullerenes. Under carefully controlled conditions, the material self-assembles to form a reproducible pattern of micron-size hexagon-shaped cells over a relatively large area (up to several millimeters).

“Though such honeycomb-patterned thin films have previously been made using conventional polymers like polystyrene, this is the first report of such a material that blends semiconductors and fullerenes to absorb light and efficiently generate charge and charge separation,” said lead scientist Mircea Cotlet, a physical chemist at Brookhaven’s Center for Functional Nanomaterials (CFN).

Furthermore, the material remains largely transparent because the polymer chains pack densely only at the edges of the hexagons, while remaining loosely packed and spread very thin across the centers. “The densely packed edges strongly absorb light and may also facilitate conducting electricity,” Cotlet explained, “while the centers do not absorb much light and are relatively transparent.”

“Combining these traits and achieving large-scale patterning could enable a wide range of practical applications, such as energy-generating solar windows, transparent solar panels, and new kinds of optical displays,” said co-author Zhihua Xu, a materials scientist at the CFN.

“Imagine a house with windows made of this kind of material, which, combined with a solar roof, would cut its electricity costs significantly. This is pretty exciting,” Cotlet said.

The scientists fabricated the honeycomb thin films by creating a flow of micrometer-size water droplets across a thin layer of the polymer/fullerene blend solution. These water droplets self-assembled into large arrays within the polymer solution. As the solvent completely evaporates, the polymer forms a hexagonal honeycomb pattern over a large area.

“This is a cost-effective method, with potential to be scaled up from the laboratory to industrial-scale production,” Xu said.

The scientists verified the uniformity of the honeycomb structure with various scanning probe and electron microscopy techniques, and tested the optical properties and charge generation at various parts of the honeycomb structure (edges, centers, and nodes where individual cells connect) using time-resolved confocal fluorescence microscopy.

The scientists also found that the degree of polymer packing was determined by the rate of solvent evaporation, which in turn determines the rate of charge transport through the material.

“The slower the solvent evaporates, the more tightly packed the polymer, and the better the charge transport,” Cotlet said.

“Our work provides a deeper understanding of the optical properties of the honeycomb structure. The next step will be to use these honeycomb thin films to fabricate transparent and flexible organic solar cells and other devices,” he said.

The research was supported at Los Alamos by the DOE Office of Science. The work was also carried out in part at the CFN and the Center for Integrated Nanotechnologies Gateway to Los Alamos facility. The Brookhaven team included Mircea Cotlet, Zhihua Xu, and Ranjith Krishna Pai. Collaborators from Los Alamos include Hsing-Lin Wang and Hsinhan Tsai, who are both users of the CFN facilities at Brookhaven, Andrew Dattelbaum from the Center for Integrated Nanotechnologies Gateway to Los Alamos facility, and project leader Andrew Shreve of the Materials Physics and Applications Division.

The Center for Functional Nanomaterials at Brookhaven National Laboratory and the Center for Integrated Nanotechnologies Gateway to Los Alamos facility are two of the five DOE Nanoscale Science Research Centers (NSRCs), premier national user facilities for interdisciplinary research at the nanoscale. Together the NSRCs comprise a suite of complementary facilities that provide researchers with state-of-the-art capabilities to fabricate, process, characterize and model nanoscale materials, and constitute the largest infrastructure investment of the National Nanotechnology Initiative. The NSRCs are located at DOE’s Argonne, Brookhaven, Lawrence Berkeley, Oak Ridge and Sandia and Los Alamos national laboratories.

The Urbee — an electric/liquid-fuel hybrid that will get the equivalent of over 200 mpg on the highway and 100 MPG in the city — is the first prototype car ever to have its entire body 3D printed, according to a Stratasys press release.

All exterior components — including the glass panel prototypes — were created using Dimension 3D Printers and Fortus 3D Production Systems, using fused deposition modeling (FDM), an additive rapid prototyping process in which a plastic filament is liquefied and extruded to form layers of a model.

In the growth of sapphire nanowires using the vapor-liquid-solid method, scientists have observed that a facet at the liquid-solid interface alternately grows and shrinks, which promotes nanowire growth. These images are from the video below. Image credit: Sang Ho Oh, et al.

From the link:

Nanowires can be grown in many ways, but one of the lesser-understood growth processes is vapor-liquid-solid (VLS) growth. In VLS, a vapor adsorbs onto a liquid droplet, and the droplet transports the vapor and deposits it as a crystal at a liquid-solid interface. As the process repeats, a nanowire is built one crystal at a time. One advantage of the VLS process is that it allows scientists to control the nanowire’s growth in terms of size, shape, orientation, and composition, although this requires understanding the growth mechanisms on the atomic scale. In a new study, scientists have investigated the steps involved in VLS growth, and have observed a new oscillatory behavior that could lead to better controlled nanowire growth.

Last month, Apple CEO Steve Jobs hinted that a big acquisition is in the works—that is, Apple might tap into its $50 billion war chest. I’ve been trying to wrap my mind around $50 billion ever since.

Also from the link; not quite a smoking gun, but it does give you something to think about:

The more intriguing acquisition target is Facebook. Jobs is probably kicking himself for not thinking up social networking. He fancies himself a cultural revolutionist wielding technology, and that’s exactly what Facebook and CEO Mark Zuckerberg have become for this next generation.

Jobs and Zuckerberg had been spotted enjoying a stroll in an obscure park near Palo Alto shortly before Jobs suggested a major acquisition may be in the works. This bit of news, reported by the Los Angeles Times, set off a whirlwind of speculation that Facebook was the target.

US approves world’s biggest solar energy project in California

October 26, 2010 by Editor

The U.S. Department of Interior approved on Monday a permit for Solar Millennium, LLC to build the largest solar energy project in the world — four plants at the cost of one billion dollars each — in southern California.

The project is expected to generate up to 1,000 Megawatts of energy, enough electricity to annually power more than 300,000 single-family homes, more than doubling the solar electricity production capacity of the U.S.

Once constructed, the Blythe facility will reduce CO2 emissions by nearly one million short tons per year, or the equivalent of removing more than 145,000 cars from the road. Additionally, because the facility is “dry-cooled,” it will use 90 percent less water than a traditional “wet-cooled” solar facility of this size. The Blythe facility will also help California take a major step toward achieving its goal of having one third of the state’s power come from renewable sources by the year 2020.

The entire Blythe Solar Power Project will generate a total of more than 7,500 jobs, including 1,000 direct jobs during the construction period, and thousands of additional indirect jobs in the community and throughout the supply chain. When the 1,000 MW facility is fully operational it will create more than 220 permanent jobs.

Mobile data traffic in the U.S. will be 35 times higher in 2014 than it was in 2009, leading to a massive wireless spectrum shortage if the government fails to make more available, the U.S. Federal Communications Commission said in a paper released Thursday.

While the paper may not get the projections exactly right, the U.S. government needs to act fast to free up more spectrum for mobile broadband, John Leibovitz, deputy chief of the FCC’s Wireless Telecommunications Bureau, said during a spectrum summit at the FCC.

“From where we sit, the numbers that we’re putting out are a matter of ‘when’ and not ‘if,'” Leibovitz said. “The demand trends are so strong, the growth is so incredible, that just overrides most of the other considerations in the analysis in the near term.”

The FCC and Congress need to move forward with plans to release more spectrum for mobile broadband, including incentives for television stations to give up their unused spectrum, added FCC Chairman Julius Genachowski. “The explosive growth in mobile communications is outpacing our ability to keep up,” he said. “If we don’t act to update our spectrum policies for the 21st century, we’re going to run into a wall — a spectrum crunch — that will stifle American innovation and economic growth and cost us the opportunity to lead the world in mobile communications.”

Ethernet is constantly evolving, but soon — in as little as five years, according to some estimates — it won’t be able to keep up with the speed and bandwidth required for applications like video and cloud computing, and distributed data storage. “Based on current traffic growth, it’s clear that 1 Terabit per second trunks will be needed in the near future,” says Stuart Elby, Vice President of Network Architecture for Verizon.

Current Ethernet technologies can’t be pushed much past 100 Gigabits per second — the speed that’s beginning to be implemented now — mainly because of the amount of power needed to run and cool the required systems, says Daniel Blumenthal, Professor of Electrical and Computer Engineering at UCSB and Director of TOEC. Large data centers can consume as much power as a small city. New generations of Ethernet need to be much more energy-efficient and cost-effective, or the power problem will limit Ethernet development, crippling the growth of key U.S. industries and technologies.

Not surprising at all. Ad buyers have an immense amount of control over how much is spent and targeting, and with all the user-provided information Facebook can seriously drill down and find an audience for any campaign.

From the link:

Chances are that at least one or two will be targeted to the activities and interests you post on Facebook, or the city you live in, your gender, or even your relationship status. These little ads are typically purchased through Facebook’s “self service” system, which enables small- and big-time advertisers to create an ad in minutes to lure specific demographic groups with a few lines of text and a graphic or photo.

Rather suddenly, these little come-ons have turned into the leading source of Facebook’s revenue. My estimates, as an analyst at eMarketer, the New York-based market research firm, show that self-service ads account for at least half of Facebook’s total ad revenue, projected to be $1.3 billion this year. That’s way more business than anyone could have expected, given that there are no upfront charges to placing these ads and that Facebook only earns revenue when viewers click on them or when a certain threshold of impressions is reached.

NASA Ames Director Simon “Pete” Worden revealed Saturday that NASA Ames has “just started a project with DARPA called the Hundred Year Starship,” with $1 million funding from DARPA and $100K from NASA.

“You heard it here,” said Worden at “Long Conversation,” a Long Now Foundation event in San Francisco. “We also hope to inveigle some billionaires to form a Hundred Year Starship fund,” he added.

“The human space program is now really aimed at settling other worlds,” he explained. “Twenty years ago you had to whisper that in dark bars and get fired.” (Worden was in fact fired by President George W. Bush, he also revealed.)

But these ambitious projects will need whole new concepts for propulsion, Worden advised. “NASA needs to build a true starship, probably using electric propulsion, probably also using solar energy and nuclear energy.

This image of a single suspended sheet of graphene taken with the TEAM 0.5, at Berkeley Lab’s National Center for Electron Microscopy shows individual carbon atoms (yellow) on the honeycomb lattice.

Also from the link:

In the current study, the team made graphene nanoribbons using a nanowire mask-based fabrication technique. By measuring the conductance fluctuation, or ‘noise’ of electrons in graphene nanoribbons, the researchers directly probed the effect of quantum confinement in these structures. Their findings map the electronic band structure of these graphene nanoribbons using a robust electrical probing method. This method can be further applied to a wide array of nanoscale materials, including graphene-based electronic devices.

“It amazes us to observe such a clear correlation between the noise and the band structure of these graphene nanomaterials,” says lead author Guangyu Xu, a physicist at University of California, Los Angeles. “This work adds strong support to the quasi-one-dimensional subband formation in graphene nanoribbons, in which our method turns out to be much more robust than conductance measurement.”

One more bit from the link, from the intro actually:

In last week’s announcement of the Nobel Prize in Physics, the Royal Swedish Academy of Sciences lauded graphene’s “exceptional properties that originate from the remarkable world of quantum physics.” If it weren’t hot enough before, this atomically thin sheet of carbon is now officially in the global spotlight.

So expect to hear a lot more about graphene in the coming months. Of course if you’re a regular reader of this blog, you’ve been getting a pretty steady (aside from the last month of light blogging) diet of graphene since almost day one (since February 2008 to be exact).

For years solar companies have wanted to make lightweight, flexible panels that are cheap to ship and easy to install (by unrolling them over large areas). But they’ve been held up by a lack of good and affordable glass substitutes.

Now 3M thinks it’s found a solution. This week the company unveiled a plastic film that it says can rival glass in its ability to protect the active materials in solar cells from the elements and save money for manufacturers and their customers.

The protective film is a multilayer, fluoropolymer-based sheet that can replace glass as the protective front cover of solar panels, says Derek DeScioli, business development manager for 3M’s renewable energy division. Manufacturers laminate the sheets onto the solar panels to seal them tight and shield them from moisture and other weather elements that can be deadly to the solar cells inside.

Solar protection: This polymer film seals out water far better than other plastics—it can protect solar panels for decades.

Arrington added that “as soon as Zuckerberg unsubscribed I lost the ability to add him to any further groups at all, another protection against spamming and pranks.”

A Facebook spokeswoman confirmed that group members can only add their friends to the group. “If you have a friend that is adding you to groups you do not want to belong to, or they are behaving in a way that bothers you, you can tell them to stop doing it, block them or remove them as a friend — and they will no longer ever have the ability to add you to any group,” she wrote in an e-mail. “If you don’t trust someone to look out for you when making these types of decisions on the site, we’d suggest that you shouldn’t be friends on Facebook.”

Twitter messages might be limited to 140 characters each, but all those characters can add up. In fact, they add up to 12 terabytes of data every day.

“That would translate to four petabytes a year, if we weren’t growing,” said Kevin Weil, Twitter’s analytics lead, speaking at the Web 2.0 Expo in New York. Weil estimated that users would generate 450 gigabytes during his talk. “You guys generate a lot of data.”

This wealth of information seems overwhelming but Twitter believes it contains a lot of insights that could be useful to it as a business. For example, Weil said the company tracks when users shift from posting infrequently to becoming regular participants, and looks for features that might have influenced the change. The company has also determined that users who access the service from mobile devices typically become much more engaged with the site. Weil noted that this supports the push to offer Twitter applications for Android phones, iPhones, Blackberries, and iPads. And Weil said Twitter will be watching closely to see if the new design of its website increases engagement as much as the company hopes it will.

I know I’m over half a week late on this (and yes, I’m aware I haven’t blogged well over a week — been crazy around these parts of late), but since I covered the topic earlier this month I thought it was interesting it’s already hit the front pages.

The issue is China essentially controlling the world’s supply of 17 rare earth metals — critical for the manufacture of electronics and military parts, to name two key examples — and how that power might be wielded. I blogged that everyone fretting about Chinese ownership of U.S. Treasuries was completely misplacing their concern. That advice has already been borne out now that China has used that control as a political bludgeon against Japan. I’m betting this is just the opening kickoff of a very serious game of political football. (Couldn’t help the metaphor there, I’m still pretty excited the NFL season is in full swing.)

From the second link:

Sharply raising the stakes in a dispute over Japan’s detention of a Chinese fishing trawler captain, the Chinese government has blocked exports to Japan of a crucial category of minerals used in products like hybrid cars, wind turbines and guided missiles.

Chinese customs officials are halting shipments to Japan of so-called rare earth elements, preventing them from being loading aboard ships at Chinese ports, industry officials said on Thursday.

The Stuxnet worm is a “groundbreaking” piece of malware so devious in its use of unpatched vulnerabilities, so sophisticated in its multi-pronged approach, that the security researchers who tore it apart believe it may be the work of state-backed professionals.

“It’s amazing, really, the resources that went into this worm,” said Liam O Murchu, manager of operations with Symantec’s (SYMC) security response team.

“I’d call it groundbreaking,” said Roel Schouwenberg, a senior antivirus researcher at Kaspersky Lab. By comparison, other notable attacks, like the one dubbed “Aurora” that hacked Google’s (GOOG) network, and those of dozens of other major companies, was child’s play.

O Murchu and Schouwenberg should know: They work for the two security companies that discovered Stuxnet exploited not just one zero-day Windows bug, but four, an unprecedented number for a single piece of malware.

Stuxnet, which was first reported in mid-June by VirusBlokAda, a little-known security firm based in Belarus, gained notoriety a month later when Microsoft (MSFT) confirmed that the worm was actively targeting Windows PCs that managed large-scale industrial-control systems in manufacturing and utility firms.

The reasons for the stagnation of U.S. broadband are multifactorial, but one of the authors, Shane Greenstein, argues that the 2003 decision allowing the broadband industry to regulate itself has caused much of the stagnation.

(For perspective, check out how much faster most of Europe and Asia is than the U.S., when it comes to broadband.)

Greenstein says that by now, broadband companies should have paid off almost all the costs associated with building out their infrastructure.

“We are approaching the end of the first buildout, so competitive pressures should have led to price drops by now, if there are any. Like many observers, I expected to see prices drop by now, and I am surprised they have not,”Greenstein told Kelogg Insight, a house organ for the university.

This means that broadband companies are now operating their broadband as almost “pure profit,” devoting only a small fraction of subscriber revenues to maintenance.

Without new entries on the market — most urban areas have at most two different broadband suppliers to choose from, the phone company and the cable company — Greenstein argues there is no incentive to lower prices.

The space project teams have developed imaginative new solutions for space and spinoffs for Earth. The AISynBio project team is working with leading NASA scientists to design bioengineered organisms that can use available resources to mitigate harsh living environments (such as lack of air, water, food, energy, atmosphere, and gravity) – on an asteroid, for example, and also on Earth .

The SpaceBio Labs team plans to develop methods for doing low-cost biological research in space, such as 3D tissue engineering and protein crystallization.

The Made in Space team plans to bring 3D printing to space to make space exploration cheaper, more reliable, and fail-safe (“send the bits, not the atoms”). For example, they hope to replace some of the $1 billion worth of spare parts and tools that are on the International Space Station.

The Cheap Access to Space team is working with NASA Ames and CalTech engineers and scientists on a radical space propulsion system using beamed microwave energy to dramatically reduce the cost of a space launch by a factor of ten.

Solving key problems for a billion people on Earth

Back on Earth, a number of teams are working on solving global problems of waste, energy, hunger, and water.

The three Upcycle teams have developed synergistic solutions to eliminate waste and reduce energy use.

The Fre3domteam is planning to bring 3D printing to the developing world to allow local communities to make their own much-needed spare parts using bioplastics.

The BioMine team is developing environmentally regenerative, safe, efficient and scalable biological methods for the extraction of metals from electronic waste. This is a multidisciplinary team with technical expertise ranging from synthetic biology and chemical engineering to computer science and biotech IP, and they are leveraging exponential advances in bioengineering, functional genomics, bioinformatics and computational modeling.

The i2cycle team focuses on developing global industrial ecosystems by upcycling one manufacturer’s waste (such as glass and ceramics) into raw material for another manufacturer (such as manufacturing tiles), conserving resources and energy in the process.

The AmundA team is developing a Web-based tool that offers data such as electricity demand and energy resources to guide suppliers in finding optimum, lower-cost, energy generation solutions. They hope to help 1.5 billion potential customers in the developing world gain access to electricity.

The H2020 team is building an intelligent, web-based platform to provide information on water to people. For example, they will use smart phones to crowd-source data about water problems, such as pollution or shortages, in communities at the “bottom of the pyramid,” and will use AI to match problems with solutions.

The Naishio (“no salt” in Japanese) team, inspired by lecturers such as Dean Kamen, plans to use nanofilters to achieve very low cost and compact, but high-volume desalination.
